  1. Let's see if your car is a petrol drinker anot. Best is to state car make and model. Sharing is caring! Currently driving a Suzuki Carry 1.3 for point A to point B.
  2. http://www.msn.com/en-us/autos/news/mazda-announces-breakthrough-in-long-coveted-engine-technology/ar-AApIOMK?li=BBnbfcL&ocid=mailsignout Mazda announces breakthrough in long-coveted engine technology Mazda Motor Corp said it would become the world's first automaker to commercialise a much more efficient petrol engine using technology that deep-pocketed rivals have been trying to engineer for decades, a twist in an industry increasingly going electric. The new compression ignition engine is 20 percent to 30 percent more fuel efficient than the Japanese automaker's current engines and uses a technology that has eluded the likes of Daimler AG and General Motors Co. A homogeneous charge compression ignition (HCCI) engine ignites petrol through compression, eliminating spark plugs. Its fuel economy potentially matches that of a diesel engine without high emissions of nitrogen oxides or sooty particulates. Mazda's engine employs spark plugs under certain conditions, such as at low temperatures, to overcome technical hurdles that have hampered commercialisation of the technology. Executive Vice President Akira Marumoto called Mazda's engine technology the automaker's "heart". The engine is called SKYACTIV-X and Mazda had no plans to supply the engine to other carmakers, Marumoto said.
  3. According to The Wall Street Journal, Japan's transport ministry said that Mitsubishi is still using altered fuel economy figures after being found out that the figures were off by as much as 8.8 percent. The cars that were affected were all supermini city cars that were meant for locals only. After being caught falsifying fuel-economy data for the four models, the company was ordered to correct the figures immediately back in April. However, they have yet to do so and the head of the ministry's road transport division, Naoki Fujii said “We cannot help but feel concerned that these points haven't been improved.” It is said in the article that Mitsubishi is aware of similar data errors dating back to 1991.
  4. Toyota's Plug-in Hybrid version of the Prius has just set a record-breaking economy run around the 20.6km Nurburgring Nordschleife with a figure of 698mpg. This equates to an astonishing 296.75km/L. Yup, this is no typo. While the official figure in the brochure says it can do 57km/L (which is also a very impressive figure on its own), it manages to return almost 300km/L because the 1.8-litre Atkinson cycle petrol engine engages only once while negotiating a long uphill climb during the lap. OK, a 20 minute and 59 second lap time is not going to impress any petrolhead but knowing your car only consumed less than five tablespoons of fuel while not going lower than the track specified minimum average speed of 60km/h probably might. The car used for the run received no special treatment except for the uprated springs, lightweight 18-inch wheels, sports bumpers all round and a rear spoiler; all available off the shelf from TRD (Toyota Racing Development). It was also wearing low resistance tyres and was fully charged before setting off. Watch the clip below to see how they managed the amazing feat. http://dai.ly/x21k17m
  5. After making its debut in the MK 7 Golf Sport, VW's new 1.4 TSI with cylinder deactivation has found its way into the hoods of the Audi A1 and A3. The primary goal of the system is to reduce fuel consumption significantly by temporarily shutting off two of the four cylinders during low to mid loads. The greatest benefits are realised while driving at constant moderate speeds. The 1.4-litre unit is also fitted with a start-stop system. The 1.4-litre engine pumps out 138bhp at 5,000 rpm and 250Nm of torque between 1,500 and 3,500 rpm. Installed in the Audi A1, the mini hatchback with S-tronic goes from 0 to 100km/h in 7.9 seconds while the Sportback version takes just 0.1 second longer. For the Audi A3 and A3 Sportback, the century sprint takes 8.3 seconds and 8.4 seconds respectively. Looking at how the new engine replaces the 'Twincharger' in the Golf Sport, it won't come as a surprise if the same thing happens for the A1 S-Line. Volkswagen is the first carmaker to implement cylinder deactivation technology in a turbocharged four-cylinder engine in large-scale production.

    An engine that could boost fuel economy by half

    If you own a car in our little sunny island, you would know about the exorbitant prices that the local petrol stations charge us. Even when oil prices go down a little, their petrol prices stays the same and there is nothing much we consumers can do about it. Would it be great if the engines in our cars can perform as per normal by using only about fifty percent of the regular fuel usage? You might think that this is something absurd or beyond the bounds of possibility but it might happen because an American company, Delphi, is developing an engine technology that could improve the fuel economy of petrol-powered cars by 50 percent. This would potentially rival the performance of hybrid vehicles while costing less. A test engine which is based on this idea is similar in some ways to a highly efficient diesel engine, but runs on petrol. The company has tested the technology in a single-piston test engine under various operating conditions. They have started testing the technology on a multi-cylinder engine which is close to a production engine. Its fuel economy estimates shows that engines based on this technology could be far more efficient than even diesel engines. These estimates are based on simulations of how a medium sized vehicle would perform with a multi-cylinder version of the new engine. The Delphi technology is the latest attempt by researchers to combine the best qualities of diesel and petrol engines. Diesel engines are 40 to 45 percent efficient in using the energy in fuel to propel a vehicle, compared to roughly 30 percent efficiency for petrol engines. But diesel engines are generally dirty and require expensive exhaust-treatment technology to meet emissions regulations. For decades, researchers have attempted to run diesel-like engines on petrol to achieve high efficiency with low emissions. Such engines might be cheaper than hybrid ones since they don't require a large battery and electric motor. In conventional petrol powered engines, a spark ignites a mixture of fuel and air. Diesel engines don't use a spark. Instead, they compress air until it's so hot that fuel injected into the combustion chamber soon ignites. Several researchers have attempted to use compression ignition with petrol, but it's proved challenging to control such engines, especially under the wide range of loads put on them as the car idles, accelerates, and cruises at various speeds. Delphi's approach, which is called petrol-direct-injection compression ignition, aims to overcome the problem by combining a collection of engine-operating strategies that make use of advanced fuel injection and air intake and exhaust controls, many of which are available on advanced engines today. For example, the researchers found that if they injected the petrol in three precisely timed bursts, they could avoid the rapid combustion that's made some previous experimental engines too noisy. At the same time, they could burn the fuel faster than in conventional petrol engines, which is necessary for getting the most out of the fuel. They used other strategies to help the engine perform well at extreme loads. For example, when the engine has just been started or is running at very low speeds, the temperatures in the combustion chamber can be too low to achieve combustion ignition. Under these conditions, the researchers directed exhaust gases into the combustion chamber to warm it up and facilitate combustion. The engineering manager of advanced powertrain technology at Delphi Powertrain suggests that the engine could be paired with a battery pack and electric motor, as in hybrid cars, to improve efficiency still more, although he also mentioned that it's not clear whether doing that would be worth the added cost.

  9. Heather Peters, a Los Angeles resident, sued American Honda Motor Co. over misleading fuel consumption figure of her 2006 Civic Hybrid and won the case. Honda claimed that the hybrid model could achieve as much as 50 miles per gallon. However, peters claimed that her Civic achieved far less than that. At the best, she could only manage 42 mpg and after receiving a software update to improve performance, fuel economy went down further to 30 mpg. The court commissioner of the Los Angeles Small Claims Court awarded her US $9867.19 in damages, which is near the maximum $10,000 allowed in small-claims court. Her victory was considered precedent setting, and legal experts said it could open the floodgates for similar cases. But it could also be one that is short-lived. In a written statement, Honda said it plans to appeal the decision. "We disagree with the judgment rendered in this case, and we plan to appeal the decision," Honda said. In appealing, Honda could take the case to superior court, where it would be allowed to use its lawyers in arguing the case. In small claims court, the California law prohibits either side from using legal representation. The fuel economy rating that Honda advertises is set by the U.S. Environmental Protection Agency. The figure is posted on the website www.fueleconomy.gov. The ratings are set according to tests that some criticize as not reflecting real-world driving. In Singapore, the National Environmental Agency (NEA) has a similar rule which states that registrable goods must carry energy labels under the Environmental Protection and Management Act (EPMA). The fuel consumption of all cars sold in Singapore can be found at the website http://app.nea.gov.sg/cms/htdocs/category_sub.asp?cid=267. However, like Peters, I believe most of the drivers here do not achieve the fuel efficiency figure as stated in the NEA website. But I think winning such a case in Singapore would be much harder.
  10. A study was recently done by J.D Power on the factors influencing car buying decision. The study was conducted from more than 24,000 US buyers of 2011 who made their purchase in 2011. Although the study was not done in Singapore, there are some interesting points that local consumer and distributors can take note. The study found that word-of-mouth is typically a critical factor in the choice a car buyer makes, yet conventional wisdom about which brands have the best quality may be sorely out of date. The study found that 40 percent of buyers said they steered clear of one brand or another because of what they had heard about quality, rather than actually checking for the latest data.

    Golf-ball like car saves fuel

    If you thought that having an ultra smooth surface that cuts through the air with razor sharp efficiency, you were wrong! As surprising as it may be, the Mythbusters on Discovery have found out that a car with dimples like those on a golf ball actually increases fuel efficiency. The original myth is that a car covered with dirt is more fuel efficient than a clean car because of the golf ball like dimpling effect that the dirt has on the car. However, they found out that dirt doesn't have any significant influence on the car's fuel efficiency. So as usual, they went to the extreme creating a car that actually had golf-ball like dimples on it by using clay. The standard car with the clay smeared on top without the dimples did 26mpg at a constant 65mph but after the dimples were created, the car did over 29mpg! The theory states that because of the dimples, it reduces the drag on the car thus making it more aerodynamic than say, a normal smooth shape. And it turns out to be Myth - Plausible. Quite amazing that they actually went out and did it. But can you imagine cars of the future looking like this just to improve a car's fuel efficiency? I don't think so but this looks amazing if you think of the principle behind it. It does look like a golf ball inspired car to the largest extent!

    Brake less and save fuel

    Fuel prices are always on the increase as our Earth's resources are being depleted and its really not the car you drive, but how you drive it. And using the brakes less saves you more money, and fuel. I've tried this and not only does it save money and petrol, it makes your driving much smoother as well. Instead of revving the engine at the lights just to get up to speed and then braking again in about 10m for another red light just wastes a ton of fuel. And by braking, its as good as dumping your fuel into the drain because you're just wasting the fuel that you used to get up to speed. So using the brakes less and controlling that heavy right hoof of yours will save you fuel. Of course you won't be going as fast but then again, why do you have to? On the expressway, maintaining a constant speed and watching out for cars braking far ahead will keep you from braking unnecessarily because you can lift off the throttle and cruise without wasting any petrol. On roads with loads of traffic lights, maybe just accelerating gradually instead of flooring the pedal could help retain some cash in your wallet.
